Abstract

BACKGROUND AND OBJECTIVE:Pneumonia is a common disease with both high morbidity and mortality, the diagnosis of pneumonia remains a clinical challenge. Many studies have been conducted to identify the usefulness of lung ultrasound for the diagnosis of pneumonia, but with inconsistent and inconclusive results. The present study aimed to establish the overall diagnostic accuracy of lung ultrasound in diagnosing pneumonia.

METHODS: Based on a comprehensive search of the Pubmed, Embase, and the Cochrane database, we identified out-come data from all articles estimating diagnostic accuracy with lung ultrasound for pneumonia. Quality was assessed with the Quality Assessment for Diagnostic Accuracy Studies. Results from different studies were pooled using a bivariate meta-analysis. Summary receiver operating characteristic curve was used to assess the overall performance of lung ultrasound-based assays.
